MLK Day is an American Federal holiday that commemorates the birth of humanitarian activist Martin Luther King Jr, who acted as the leader of the African-American Civil Rights movement from the mid-1950s until his death by assassination in 1968. His involvement in the campaign was fundamental to its success in ending the legal segregation of African-Americans in the South and other parts of the US and he was awarded the Nobel Peace Prize in 1964.

Before that, however, King became a figure in the public eye as head of the Southern Christian Leadership Conference, which promoted non-violent strategies to address, and hopefully resolve, conflicts. One instance where he showcased these viewpoints was the massive March on Washington (1963), to achieve civil rights.

An influential man, and well-known for his public speeches and wise words, King coined many inspirational phrases over his short but inspiring time in the limelight. While he was born on 15 January 1929, MLK Day is marked on the third Monday of the year, so to celebrate, IBTimes UK has compiled some of his best quotes to remember both his life and his career...
